Abstract: <div class="section abstract"><div class="htmlview paragraph">Electronic control units of Bendix® ABS/ESC and Collision Mitigation Systems have the capability to record event data in the ABS/ESC control unit. Bendix refers to this event data recording functionality as the Bendix Data Recorder (BDR). This paper presents an overview of the BDR functionality and examines the range and resolution of data elements, the synchronicity or timing of the recorded data, and application of the data for use in … Show more

<div class="section abstract"><div class="htmlview paragraph">The Daimler Detroit Assurance<sup>Ⓡ</sup> 4.0 collision mitigation system is able to assist a driver in various aspects of safely operating their vehicle. One capability is the Active Brake Assist (ABA), which uses the Video Radar Decision Unit (VRDU) to communicate with the front bumper-mounted radar to provide information about potential hazards to the driver. The VRDU may warn the driver of potential hazards and apply partial or full braking, depending on the data being gathered and analyzed. The VRDU also records event data when an ABA event occurs. This data may be extracted from the VRDU using Detroit DiagnosticLink software. This paper presents an overview of the VRDU functionality and examines aspects of VRDU data such as the range and resolution of data elements, the synchronicity or timing of the recorded data, and application of the data for use in the analysis of crashes. Various tests were performed using a truck equipped with Detroit Assurance<sup>Ⓡ</sup> 4.0 in a manner designed to trigger VRDU records. VRDU data was compared to data collected from the J1939 CAN Bus and from a Racelogic VBOX 3i 100 Hz GPS Data logger.</div></div>

<div class="section abstract"><div class="htmlview paragraph">The Bendix Wingman Fusion – a radar and camera collision mitigation system (CMS) available on commercial vehicles – was evaluated in two separate test series to determine its performance in simulated rear collision scenarios. In the first series of tests, evaluations were conducted in daytime, nighttime, and rainy conditions between 15 to 58 miles per hour (mph) to evaluate the performance of the audible and visual forward collision warning (FCW) system in a first-generation Bendix Wingman Fusion CMS while approaching a stationary live vehicle target (SLVT) in a 2017 Kenworth T680. A second test series was conducted with a 2017 Kenworth T680 traveling at 50 mph in daytime conditions approaching a decelerating vehicle to evaluate the Bendix Wingman Fusion CMS on the truck. Both test series sought to determine the maximum distance the system would warn prior to the test driver swerving around the SLVT or moving vehicle target. The first test series utilized a 2014 Ford F150 as the SLVT and the second test series utilized a 2014 Lexus RX350 as a Decelerating Vehicle Target. Testing measured the time to collision (TTC) values of the issuance of the audible/visual FCW utilizing VBOX data acquisition equipment. The results of the two series of tests provide valuable information about the performance of the Bendix Wingman Fusion CMS approaching stationary and decelerating vehicles in rear collision scenarios.</div></div>
